Your Skin Holds Everything Together

Your Skin Holds Everything Together, but that's not all

You can go online and get all the factual information you want on every part of the human body. Put in the word “skin,” and you will be amazed at how much information there is about human skin. One comic said, “Your skin holds everything together.” In truth, it does much more than that.

We tend to classify humans based on their skin color, but our skin color is related to the needs of the body. Black objects radiate heat more efficiently than white objects. Take two identical cans and paint one black and the other white. Heat them to the same temperature and then let them sit in an insulated environment. The black can will cool off faster than the white can. Dark skin color is due to a biological pigment called melanin. Melanin absorbs ultraviolet light and thus protects the body. People living in tropical areas where they are exposed to more heat and ultraviolet light have more melanin than people living in cooler regions. There is, therefore, a latitude effect on skin color.

The more you study the design of your skin, the more amazing it is. One square inch of human skin contains nearly 20 million cells and 625 sweat glands. That square inch of skin can also have as many as 65 hairs, 19 feet (5.8 meters) of blood vessels, and 19,000 sensory cells. To limit bleeding, blood vessels in your skin temporarily shrink instantly if the skin is cut or if pressure is applied. Your body sheds skin cells when they die and replaces them with new ones. Three-quarters of the dust floating around your house is made up of dead skin cells.

So, if you think your skin holds everything together, and that’s all, you would be wrong. Your skin, the largest organ in your body, does a wide range of things that help you to stay alive and comfortable. When David wrote, “I will praise you, God, for I am fearfully and wonderfully made” (Psalms 139:14), he was not aware of many things about our bodies that we know today. As we look at ourselves with tools such as microscopes, we see design in the construction of our bodies that David could not have imagined.

There is a wonderful book published in 1989 and now out of print that gives many other examples of the incredible designs we see in our bodies. The title is The Compass in Your Nose and Other Astonishing Facts About Humans by Marc McCutcheon and published by Jeremy Tarcher, Inc.

Race and Skin Color

Race and Skin ColorWhy do humans have different races and skin colors? If we all came from “Mother Eve,” should we not all be the same color? In the past, some people suggested that people of other races were not really human, and they used that argument to justify everything from slavery to infanticide. What is the truth about race and skin color?

It is interesting scientifically that only humans have mostly naked skin and along with that, different colors of skin. Other animals have hair and mostly light-colored skin. As science has told us more about skin color and confirmed that we all came from common ancestors, we find clues about race and skin color and how we should treat one another.

The most fundamental reason for skin color differences is the fact that humans live at different latitudes. It is quite evident that human populations that have lived near the equator for many generations tend to have darker skin. As one moves from equatorial Africa toward the north, there is a constant change in skin color. By the time you get to northern Scandinavia, you have very light-skinned people with blond hair and blue eyes. People living near the equator have black skin, black eyes, and black hair.

It’s easy to understand why. Take two tin cans and paint one black and the other white. Fill them with boiling water and measure their temperature five minutes later. Dark colors radiate heat faster than light ones, so the darker can will be cooler than the white one. In equatorial Africa, the problems of heat release are very significant, because our brain cannot be allowed to overheat.

Another factor is ultraviolet radiation from the Sun, which can cause many changes in living tissue, including cancer. Human skin produces a substance known as melanin for protection. Melanin, God’s sunscreen, is a large organic molecule which both physically and chemically reduces the effects of UV radiation. Melanin absorbs UV rays causing them to lose energy. It also neutralizes harmful chemicals called free radicals that form in the skin after damage from UV radiation.

Dark skin absorbs a high percentage of UV light. It is essential, however, not to lose all the UV. Another thing that UV light does is to allow the body to produce vitamin D. Farther from the equator, the amount of UV is less, so dark-skinned people may not get enough UV light to make vitamin D. Lack of vitamin D causes rickets, so lighter skin is better at latitudes away from the equator.

As humans have migrated all over the globe, their ability to produce nutrients like vitamin D has been reduced in some groups. The Inuit people in Alaska don’t get enough vitamin D from the Sun, but they eat fish, which is very high in vitamin D. Their diet compensates for the low UV exposure. The presence of melanin in the skin, the complex biochemical system that produces vitamin D, and the ability of the body to protect itself against overheating and nutritional problems all speak well of the wisdom and design of our bodies.

Psalms 139:14 says, “I will praise you, Lord, for I am fearfully and wonderfully made.” Instead of allowing race and skin color to divide and cause hostility between us, we should celebrate God’s wisdom and design. They show that we have a universal Creator who designed and equipped us marvelously to live on a planet that has varied conditions and environments.

Largest Body Organ

Largest Body Organ - Skin
As you think about all of the organs in your body and how important they are, don’t forget the largest body organ. It’s also the one that is most visible—your skin.

Have you ever considered how incredible your skin is? The hands of a laborer may be rough like sandpaper, but his abdominal skin could be smooth and soft. The calves of your legs have skin bonded tightly to a muscle layer. The skin on your elbow can be lifted loosely in rolls. If you used a microscope to examine the skin of our scalp, lip, heel, and finger, you might think you were studying sample from different species.

Your skin is the largest body organ, and there is no other organ like it. It flexes, folds, stretches, and bends around joints. It’s sensitive to touch. The skin of your finger pads is sensitive enough to detect a grain of dust on a smooth surface or read Braille letters in a book. When you blush (something that only humans do), the blood vessels of your skin suddenly rush many times more blood than usual. Your skin even regenerates itself when it’s damaged.

Your skin shows emotions, cools and insulates your body, protects you from germs, serves as a receptor for all kinds of stimuli, and gives you that unique appearance. We often cut off the hair growing out of our skin or add some substance to soften and beautify our skin. We seldom take a moment to realize what a fantastic organ it is.

Of all the vital organs of your body, your skin is the most visible. Skin color or texture may vary from person to person, but regardless of those factors, it protects what is inside. Your largest body organ is another incredible design by a Master Designer.

Human Species and Racial Differences

Human Species and Racial Differences
One of the oldest controversies among anthropologists is over whether a “splitter” view or a “lumper” view is the most accurate description of human history. As scientists study ancient fossils, they have to determine whether they should be split into different species of hominids or lumped into races of one human species. One of the famous splitters was Louis Leakey who attached a new name to every find he made. Because of his long and productive life in studying the fossils of Africa his names have stayed around for a long time.

Other anthropologists have suggested that many of the specimens with unique names were actually just racial variations. Races can look very different and yet still be one species. There is just one human species. Looking at the skeletal remains of a Pygmy and a Swede, one might conclude that they are two different species, but they are fertile with one another, and they are one species. Racial characteristics are usually related to climate. Skin color is related to how close to or how far from the equator ones’ ancestors have lived. Lighter skin color can absorb more vitamin D from limited sunlight, and dark skin gives greater protection from the harmful rays of the Sun.

All of this has been getting attention recently as scientists study the DNA of the remains of various humans. The London Natural History Museum has just released a study of the DNA of the so-called “Cheddar Man”–a human skeleton discovered in Cheddar Gorge, Somerset, England, in 1903. The study suggests that this person had dark skin, blue eyes, and curly hair. The theory is that the British landmass was connected to continental Europe and that humans migrated into the area with some of them coming all the way from Africa.

The Bible makes it clear that there is one human species. The apostle Paul said in Acts 17:26 God “has made of one blood all nations of men to dwell on the face of the Earth.” What distinguishes humans as a species is that God created us in His image which gives us the ability to worship and have creativity and a concept of self. Our physical characteristics which identify us racially are simply functions of genetic heritage and the environment in which we live. Racial prejudice comes from ignorance, and Christians should be leaders in demanding equality for all people.

Different Shades of Brown

Different Shades of Brown
Racial prejudice based on skin color is a function of ignorance. I am amazed that promoters of violence against black-skinned people have daughters who are using tanning booths to get darker. There is no inferior race, and there are no different species of humans. Acts 17:26 tells us that God “has made of one blood all nations of men for to dwell on all the face of the earth…” We are all just different shades of brown.

Many years ago the preacher of the Central Church of Christ in Birmingham, Alabama, invited me to participate in a television panel discussion. The format was a call-in where callers could ask questions for the panel to answer. On the panel with me was the black president of a small African-American college in East Texas.

The discussion took place during the time of racial strife in Birmingham. A caller asked if black people were evolved apes and white people were created by God in His image. I responded by pointing out that apes and white people have more features in common than apes and black people. This includes hair texture, jaw shape, skull shape, and even skin color when you look under the hair. This produced some antagonism from our host but was followed by the question of why black people are black and white people are white.

I took my hand and laid it on a white sheet of paper and asked if I was really white? The answer, of course, was that I wasn’t white like the paper. I was light brown. Then I asked my black friend to lay his hand on the same sheet of paper, and I asked if he was really black? The answer was obvious. He was just a darker shade of brown. I then made the point that we are all just different shades of brown, and we are all equally created in God’s image.

My black friend leaned over and whispered in my ear as we looked into some rather hostile people at the TV station. He said, “Ain’t neither one of us getting out of here alive.” I am glad to say that we did.
